NOTE:
Under no circumstances should oil change inter -
vals exceed 8,000 miles (12,875 km) or six months, whichever comes first when using
biodiesel blends greater than 5% (B5).
The owner is required to monitor mileage for
B6-B20 biodiesel, the automatic oil change indi -
cator system does not reflect the use of
biofuels.
Fuel filter change interval is maintained at every
second oil change. This is especially important
with biodiesel usage.
For more information on using biodiesel

1. Under normal conditions the diesel fuel filter should be replaced every 20,000 miles (32,000 km) (every other oil change). If the vehicle is being used in severe operating conditions,
or In certain geographical areas of the country (Pennsylvania, New York, Ohio, Maryland, West Virginia, Arkansas, Oklahoma, Kansas, Iowa, Missouri and Nebraska) due to fuel
cleanliness issues, it’s recommended to replace the fuel filter every 10,000 miles (16,000 km).

WARNING!
You can be badly injured working on or around
a motor vehicle. Do only service work for
which you have the knowledge and the right
equipment. If you have any doubt about your
ability to perform a service job, take your
vehicle to a competent mechanic.
Failure to properly inspect and maintain your
vehicle could result in a component malfunc -
tion and effect vehicle handling and perfor -
mance. This could cause an accident.

CHECKING OIL LEVEL
To ensure proper engine lubrication, the engine oil
must be maintained at the correct level. Check the
oil level at regular intervals, such as every fuel
stop. The best time to check the engine oil level is
about five minutes after a fully warmed up engine
is shut off.
Checking the oil while the vehicle is on level ground
will improve the accuracy of the oil level readings.
There are four possible dipstick types:
Crosshatched zone.
Crosshatched zone marked SAFE.
Crosshatched zone marked with MIN at the low
end of the range and MAX at the high end of the
range.
Crosshatched zone marked with dimples at the
MIN and the MAX ends of the range.
NOTE:Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 quart (1.0 liter) of oil when the reading is
at the low end of the dipstick range will raise the oil
level to the high end of the range marking.
ADDING WASHER FLUID
The fluid reservoir is located under the hood and
should be checked for fluid level at regular
intervals. Fill the reservoir with windshield washer
solvent only (not radiator antifreeze). When
refilling the washer fluid reservoir, take some
washer fluid and apply it to a cloth or towel and
wipe the wiper blades clean. This will help blade
performance.
To prevent freeze-up of your windshield washer
system in cold weather, select a solution or mixture
that meets or exceeds the temperature range of
your climate. This rating information can be found
on most washer fluid containers. After the engine has warmed up, operate the
defroster for a few minutes to reduce the
possibility of smearing or freezing the fluid on the
cold windshield. Windshield washer solution used
with water as directed on the container, aids
cleaning action, reduces the freezing point to avoid
line clogging, and is not harmful to paint or trim.
CAUTION!
Overfilling or underfilling the crankcase will
cause oil aeration or loss of oil pressure. This
could damage your engine.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite and
burn you. Care must be exercised when filling or
working around the washer solution.

408SERVICING AND MAINTENANCE
MAINTENANCE-FREE BATTERY
Your vehicle is equipped with a maintenance-free
battery. You will never have to add water, and
periodic maintenance is not required.
PRESSURE WASHING
Cleaning the engine compartment with a high
pressure washer is not recommended.
VEHICLE MAINTENANCE
An authorized dealer has the qualified service
personnel, special tools, and equipment to
perform all service operations in an expert
manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals before
attempting any procedure yourself.
NOTE:Intentional tampering with emissions control
systems may void your warranty and could result in
civil penalties being assessed against you.
WARNING!
Battery fluid is a corrosive acid solution and
can burn or even blind you. Do not allow
battery fluid to contact your eyes, skin, or
clothing. Do not lean over a battery when
attaching clamps. If acid splashes in eyes or
on skin, flush the area immediately with large
amounts of water Úpage 384.
Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not
use a booster battery or any other booster
source with an output greater than 12 Volts.
Do not allow cable clamps to touch each
other.
Battery posts, terminals, and related accesso -
ries contain lead and lead compounds. Wash
hands after handling.
CAUTION!
It is essential when replacing the cables on
the battery that the positive cable is attached
to the positive post and the negative cable is
attached to the negative post. Battery posts
are marked positive (+) and negative (-) and
are identified on the battery case. Cable
clamps should be tight on the terminal posts
and free of corrosion.
If a “fast charger” is used while the battery is
in the vehicle, disconnect both vehicle battery
cables before connecting the charger to the
battery. Do not use a “fast charger” to provide
starting voltage.
CAUTION!
Precautions have been taken to safeguard all
parts and connections however, the pressures
generated by these machines is such that
complete protection against water ingress
cannot be guaranteed.
WARNING!
You can be badly injured working on or around a
motor vehicle. Only do service work for which
you have the knowledge and the proper
equipment. If you have any doubt about your
ability to perform a service job, take your vehicle
to a competent mechanic.

ENGINE OIL — GAS ENGINE
Engine Oil Selection — Gasoline Engine
Use only the manufacturer's recommended fluids
Úpage 473.
NOTE:Hemi engines (5.7L) at times can tick right after
startup and then quiet down after approximately
30 seconds. This is normal and will not harm the
engine. This characteristic can be caused by short
drive cycles. For example, if the vehicle is started
then shut off after driving a short distance. Upon
restarting, you may experience a ticking sound.
Other causes could be if the vehicle is unused for
an extended period of time, incorrect oil, extended
oil changes or extended idling. If the engine
continues to tick or if the Malfunction Indicator
Light (MIL) comes on, see the nearest authorized
dealer.
Engine Oil Selection — Diesel Engine
Use only the manufacturer's recommended fluids
Úpage 473.
American Petroleum Institute (API)
Approved Engine Oil
These symbols mean that the oil has been certified
by the API. The manufacturer only recommends API
trademark oils.
The API Starburst trademark certifies
0W-20, 0W-30 and 5W-30 engine oils.
The API Donut trademark certifies 0W-40
and 5W-40 engine oil.
Synthetic Engine Oils
Your engine was designed for synthetic engine oils,
only use synthetic API approved engine oils.
Synthetic engine oils which do not have both the
correct API trademark and the correct SAE viscosity
grade numbers should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends against
the addition of any additives (other than leak
detection dyes) to the engine oil. Engine oil is an
engineered product and its performance may be
impaired by supplemental additives.
Disposing Of Used Engine Oil And Oil
Filters
Care should be taken in disposing of used engine
oil and oil filters from your vehicle. Used oil and oil
filters, indiscriminately discarded, can present a
problem to the environment. Contact an
authorized dealer, service station or governmental
agency for advice on how and where used oil and
oil filters can be safely discarded in your area.
ENGINE OIL FILTER
The engine oil filter should be replaced with a new
filter at every engine oil change.
Engine Oil Filter Selection
A full-flow type disposable oil filter should be used
for replacement. The quality of replacement filters
varies considerably. Only high quality Mopar®
certified filters should be used.
CAUTION!
Do not use chemical flushes in your engine oil as
the chemicals can damage your engine. Such
damage is not covered by the New Vehicle
Limited Warranty.
